Notes

Photos taken 6/10/24 around 1pm. Wet slab in Republic Creek south of Cooke. I estimate 10-20’ deep and 1000’+ wide. The past 5-6 days have been warm, and previous night there was steady rain all night into the mid morning, so not out of the question that it happened within 24 hrs, likely within the last 1-3 days.

    • Long-running wet sluff at Black Mtn

    Date
    Activity
    Snowboarding

    Skinned up the large NW snowfield on Black Mountain on Saturday July 6 to lap what remained. Surprisingly, coverage was very good. We descended just after 11am. Turns on the shallower sun-exposed aspects on the way down triggered large sluffs which ran for ~200ft on the top 2-3 inches of the snow.

    Notes

    From IG messages on June 1 2024: "there were two riders and a dog on the slope. One rider was partially caught and rode out when everything stopped moving. The dog was very afraid and got stuck at the crown and rocks on the lookers left. Happened about 3pm today within the first 20 riders. Started with a small slide and propagated much larger when it got closer to the rocks."

    From antoher ob. "At approximately 15:40 a D3 avalanche on the Gardiner headwall broke.  It was triggered by a snowboarder and his dog.  The run had already been tracked by skis and snow machines but the trigger point was slightly farther skier right and appeared to trigger a convex wind slab. Several skiers, boarders, and riders were in the area but there were no burials or injuries"
